Oxycodone interactions with other drugs

Brian A Baldo
Drugs may cause serotonin toxicity by a number of different mechanisms including inhibition of serotonin uptake and metabolism, increased serotonin synthesis and release, activation of serotonin receptors, and inhibition of cytochrome P450 oxidases. Some drug interactions involving opioids can increase intrasynaptic levels of serotonin, and opioid analgesic drugs are now recognized as being involved in some cases of serotonin toxicity especially if administered in conjunction with other serotonergic medications including monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, and tricyclic antidepressants...

BACKGROUND Oxycodone is a semisynthetic opioid receptor agonist, and is frequently used for pain control in patients with cancer. Most oxycodone is metabolized by N-demethylation to noroxycodone by CYP3A. Rifampin is a strong inducer of several drug-metabolizing enzymes, including CYP3A. Hence, rifampin-induced CYP3A activity may decrease the effect of oxycodone. CASE REPORT Osteosarcoma is a highly aggressive primary bone tumor of childhood and adolescence. Here, we report a 30-year-old male with osteosarcoma of the femur with lung metastases in the upper lobe...

BACKGROUND: Variation in the CYP2D6 gene may affect response to opioids in both poor and ultrarapid metabolizers, but data demonstrating such associations have been mixed, and the impact of variants on toxicity-related symptoms (e.g., nausea) is unclear. Therefore, we examined the association between CYP2D6 phenotype and poor pain control or other adverse symptoms related to the use of opioids in a sample of primary care patients. MATERIALS AND METHODS: We identified all patients in the Mayo Clinic RIGHT Protocol who were prescribed an opioid medication between July 01, 2013 and June 30, 2015, and categorized patients into three phenotypes: poor, intermediate to extensive, or ultrarapid CYP2D6 metabolizers...

Low dose naltrexone (LDN) has been evaluated in several small studies for the treatment of inflammatory conditions. It is thought to work through modulation of inflammatory mediators and upregulation of endogenous opioid receptors. This may hypersensitize patients to exogenous opioids. Drug-drug interaction screening tools built into electronic health records and other services identify the interaction as risk of opioid withdrawal rather than hypersensitivity. We present a case of a drug-drug interaction in a patient who was receiving LDN treatment of multiple sclerosis...

Pain is a common symptom in older people. It is possible that pain is underreported in older persons due to an incorrect belief that it is an inevitable part of aging. Opioid analgesics are potent medications, with confirmed efficacy for the treatment of moderate to severe pain. These drugs are commonly used in older persons. However, there is insufficient evidence regarding safety of opioids in older patients. One of the reasons for this is the lack of randomized, controlled clinical trials. People of advanced age often have comorbidites and use other prescription drugs, as well as over-the-counter (OTC) compounds, thus making them more suceptible to the risk of interactions with opioids...

BACKGROUND: Little is known about the effects of human fetal exposure when a new drug is authorized unless it was specifically developed for use in pregnancy. Since many factors may contribute to adverse fetal effects, having comprehensive information about in utero exposures will enhance our ability to make correct determinations about causality. OBJECTIVE: The objective of the study was to assess the extent to which women, recruited without the intervention of health care professionals (HCPs), will provide information, suitable for research purposes, via the Internet or by phone on some potential risk factors in pregnancy...

Purpose Aprepitant and its parenteral formulation fosaprepitant are widely used for the prevention of chemotherapy-induced nausea and vomiting. Aprepitant exerts modest inhibitory effect on CYP3A4 and modest inductive effect on CYP2C9 substrates such as some antineoplastics and multiple other medications. This article is aimed to provide pharmacists and other healthcare professionals with an updated summary of drug-drug interactions of aprepitant/fosaprepitant and implications for clinical practice. Method We reviewed publications reporting drug-drug interactions between aprepitant/fosaprepitant and other medications...

AIMS: Activation of PPARγ by pioglitazone (PIO) has shown some efficacy in attenuating addictive-like responses in laboratory animals. The ability of PIO to alter the effects of opioids in humans has not been characterized in a controlled laboratory setting. The proposed investigation sought to examine the effects of PIO on the subjective, analgesic, physiological and cognitive effects of oxycodone (OXY). METHODS: During this investigation, nondependent prescription opioid abusers (N=17 completers) were maintained for 2-3weeks on ascending daily doses of PIO (0mg, 15mg, 45mg) prior to completing a laboratory session assessing the aforementioned effects of OXY [using a within-session cumulative dosing procedure (0, 10, and 20mg, cumulative dose=30mg)]...

Skin ulcers are a common issue in the elderly, as physiological loss of skin elasticity, alterations in microcirculation, and concomitant chronic diseases typically occur in advanced age, thereby predisposing to these painful lesions. Wound-related pain is often associated with skin ulcers and negatively impacts both the patient's quality of life and, indirectly, wound healing. Pain management is an ongoing issue in the elderly, and remains underestimated and under-treated in this fragile population. Recent guidelines suggest the use of opioids as the frontline treatment of moderate and severe pain in nononcological pain in the elderly...

Persistent pain affects the elderly disproportionally, occurring in 50% of elderly community-dwelling patients and 80% of aged care residents. The management of pain in the elderly and frail patient is complicated because of the risks posed by changes in pharmacokinetics and pharmacodynamics, polypharmacy, and drug-disease interactions. Trials evaluating the efficacy of analgesics have often excluded elderly patients and universally excluded frail patients; therefore, the true efficacy and side-effect profiles in these population groups are largely unknown, especially for long-term use...

The transport of opioid analgesics across the blood-brain barrier (BBB) is an important determinant of their therapeutic effects. The human brain is protected by the BBB, which consists of brain capillary endothelial cells linked with tight junctions. It is well established that the polarized expression of numerous transporters and receptors at the brain capillary endothelial cells controls the blood-brain exchange of nutrients, waste products deriving from neurotransmitter substances, and drugs. Morphine is a substrate of P-glycoprotein and the P-glycoprotein-mediated efflux transport at the BBB maintains a lower unbound concentration of morphine in the brain compared with plasma...

Serotonin syndrome is a potentially life-threatening condition caused by excessive central and peripheral stimulation of serotonin brainstem receptors, usually triggered by inadvertent interactions between agents with serotonergic activity. Evidence supporting an association between nonserotonergic opiates, such as oxycodone or morphine, and serotonin syndrome is very limited and even contradictory. In this case report, we describe a patient who developed serotonergic-adverse effects likely precipitated by an interaction between morphine and phenelzine...

Opioid-related mortality rates have escalated. Drug interactions may increase blood concentrations of the opioid. We therefore used human liver microsomes (HLMs) and cDNA-expressed human cytochrome P450s (rCYPs) to study in vitro inhibition of buprenorphine metabolism to norbuprenorphine (CYP3A4 and 2C8), oxycodone metabolism to noroxycodone (CYP3A4 and 2C18) and oxymorphone (CYP2D6), and methadone metabolism to R- and S-2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP; CYP3A4 and 2B6). In this study, we have examined the inhibitory effect of 12 (mostly antifungal) azoles...

PURPOSE: We present a database of prescription drugs and international normalized ratio (INR) data and the applied methodology for its use to assess drug-drug interactions with vitamin K antagonists (VKAs). We use the putative interaction between VKAs and tramadol as a case study. METHODS: We used a self-controlled case series to estimate the incidence rate ratio (IRR) comparing the rate of INR measurements of ≥4.0 in concomitant tramadol and VKA-exposed periods to VKA-only-exposed periods...

It has been shown that newly initiated opioid therapy increases the risk of fall-related injuries. Yet, it remains to be determined whether drug-drug interactions can affect this negative effect, for instance with drugs inhibiting cytochrome P4502D6 (CYP2D6) that metabolizes codeine and also has a partial effect on tramadol and oxycodone. Our aim was to investigate how CYP2D6-inhibiting drugs contribute to explaining the risk of fall-related injuries for newly initiated opioid treatments with codeine, tramadol or oxycodone...

This study examined zolpidem and concurrent opioid, benzodiazepine, other central nervous system (CNS) depressants, and alcohol use. Urine specimens were analyzed using liquid chromatography-mass spectrometry (LC-MS/MS). Specimens were tested for zolpidem (n = 71,919) and separated into a provider-reported medication list documenting (n = 5,257) or not documenting zolpidem use (n = 66,662). Zolpidem-positive specimens were further separated into reported and unreported use cohorts. The total number of zolpidem-positive specimens in the reported and unreported use cohorts was 3,391 and 3,190, respectively...

BACKGROUND: Rifampin is a potent inducer of both cytochrome P-450 oxidative enzymes and the P-glycoprotein transport system. Among numerous well documented, clinically significant interactions, examples include warfarin, oral contraceptives, itraconazole, digoxin, verapamil, simvastatin, and human immunodeficiency virus-related protease inhibitors. Rifabutin reduces serum concentrations of antiretroviral agents, but less so than rifampin. Rifapentine is also an inducer of drug metabolism...

Opioids are increasingly used to manage not only acute but also chronic pain and heroine addiction. These patients usually receive many other medications that can interfere with the effects of opioids and vice versa. Patients often need combinations of drugs for their pain management, for treating opioid-related adverse effects or for other indications including depression and anxiety. Several antibiotics can also have interactions with opioids. It is important to understand what potential interactions exist between opioids and other drugs...
